Abstract

The structural responses in collisions and grounding are highly nonlinear. They not only involve buckling and plastic collapse, but also crushing and fracture. By nature, the effects of loading speed or strain rates significantly affect the structural responses in collisions or grounding. The nonlinear structural responses involving crushing and fracture as well as buckling and plastic collapse are often called structural crashworthiness. The primary objective of structural crashworthiness analysis under dynamic and impact loading is to compute structural deformations or damage and associated reaction forces with time. Subsequently, the relationships between deformations and accidental forces are determined. The absorbed energy characteristics of structures in accidental loads can be calculated by integrating the area below the accidental force-deformation curve. This chapter describes computational modeling practices for structural crashworthiness analysis in collisions and grounding.
